What I Used:
OnGuard, Thieves, ect. (whatever oil blend this is depending on the carrier) If you don't own this, you can follow the recipe to make it in my post Thieves Essential Oil: A Winter Necessity.
Eucalyptus Essential Oil
Tea Tree Essential Oil (or Melaleuca)
What I did:
I mixed 2-3 drops tea tree eo with a carrier oil and rubbed it into my neck to aid in the healing of my sore throat.
I mixed 4-5 drops thieves eo with a carrier oil and rubbed it into the bottoms of my feet for quick absorption into my system.
I mixed 3-5 drops eucalyptus eo with a carrier oil and rubbed it into my chest as a make shift vapor rub to help with my cough and congestion.
That's it. That's all I did to kick my cold to the curb. In two days I was able to completely knock out my sore throat, and my cold is almost completely gone!
